Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed May 23, 1906. Serial No. 318,298.

To all whom it may concern:

Be it known that I, WILLIAM S. WALKER, a resident of Knoxville borough,in the county of Allegheny and State of Pennsylvania, have invented anew and useful Improvement in Brushes; and I do hereby declare thefollowing to be a full, clear, and exact description thereof.

My invention relates to brushes and has for its object to provide abrush which will be cheap and strong in its construction, can be made inany size, and will not get out of order by the parts becoming loose orseparated.

My invention consists, generally stated, in the novel arrangement,construction and combination of parts, as hereinafter more specificallydescribed and partic ularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains toconstruct and use my improved brush, I will describe the same morefully, referring to the accompanying drawing, in which Figure 1 is avertical central section of my improved brush. Fig. 2 is a like view ofthe same taken at right angles to that shown in Fig. 1 and on the line2-2 on said Fig. 1. Fig. 3 is a bottom view of the same cutting throughthe bristles and on the line 3-3 Fig. 1 looking in the direction of thearrow. Fig. 4 is a like view with the plug and bristles removed. Fig. 5is a perspective view of the plug. Fig. 6 is a perspective view of theferrule.

Like symbols of reference herein indicate like parts in each of thefigures of the drawing.

As illustrated in the drawing 1 represents the handle of the brush whichis widened at the brush end to any desired uddth for producing a body orbase 2 to which the bristle-holding devices are attached.

A metal band or ferrule 3 is fitted around the base 2 and projectstherefrom to form a cavity 4 for the reception of the bristles 5, andsuch ferrule is formed with the integral cross-bars 6 extending acrossand connecting the sides 7 of the ferrule. These crossbars (3 areadapted to fit within seats or slots 8 formed in the bottom face 9 ofthe base 2 and before the bristles are put in place staples 10 areplaced over the same and driven into the base 2 bypressure against thesame to hold the ferrule in place on said base.

The device for holding the bristles 5 in place consists of a metalclamping bar or plug 11 preferably formed of aluminium, which plug isadapted to fit within the cavity 4 of the ferrule 3 and lengthwisethereof. The plug 11 has its sides 12 tapered or inclined inwardlytowards its inner face and is provided with pointed anchoring pins 13formed integral with said plug and projecting from such inner face inorder to be driven into the base 2 beyond the staples 10 to hold saidplug in place. A pointed wire pin or nail 14 is driven through anopening 11 in the center of the plug 11 and into the base 2 in order toassist in holding said plug in place by its head 15 fitting against theouter face of said plug.

In making a brush, the ferrule 3 is first put around the base 2, itscross bars 6 being seated in the grooves 8 of the base. The staples 10are then driven into the base over the bars 6, securely attaching thebase and ferrule together. The bristles 5 are now placed in position andsecurely confined between the ferrule and the sides of the clampingplate by forcing the prongs 13 of the latter into the base by pressurebrought to bear against the outer face of the plate. Then the loose nail14 is placed in the hole 11 of the clamping plate and driven into thebase to further assist in securing the plate to the base. It will thusbe seen that there is provided a most substantial and effective means ofsecuring the ferrule to the base or handle and for secru'ing thebristles to the brush, the parts of which are cheap and simple tomanufacture and very easy and quick to assemble. The plug is driven intoplace under heavy pressure of about two thousand pounds so that when itis seated it bears outwardly against the bristles on all sides and bindsthem against the inner sides and ends of the ferrule with great force,so that the bristles are thus securely held against any dislodgment.Practical experience has proven that the device provides for the usualor regular length of bristles extending out of the ferrule, but shorterbristles can be used than in the ordinary constructions, thereby makinga saving of about one-fourth in the cost of the bristles, while in themanufacture of the brush about one-third less of skilled labor isrequired than in the ordinary constructions.

My improvement affords means for making a brush of any desired width bylengthening or shortening the ferrule, increasing or decreasing thenumber of crossbars, the plug and anchoring-pins thereon, while withinthe scope of my invention as defined in the claims many changes in thefornr and construction of the various parts may be made by the skilledmechanic without departing from the spirit of the invention orsacrificing any of its advantages.

What I claim as my invention and desire to secure by Letters Patentis 1. In a brush, the combination of a handle base provided with slotsor grooves extending transversely of the bottom thereof, a ferruleextending around said base and having integral crossbars fitting withinsaid grooves, said ferrule being fastened to said base by staplesfitting over said 105 cross-bars and driven into the base, a clampingplate, bristles confined between said clamping plate and said ferruleand means for attaching said clamping plate to said base; substantiallyas described.

2. In a brush, the combination of a handle base provided 110 withgrooves extending transversely of the bottom thereof, a ferruleextending around said base and having integral cross-bars fitting withinsaid slots, said ferrule being fastened to said base by staples fitting;over said crossbars and driven into the base, a clamping plate, 115

bristles confined between said clamping plate and said i'errule, saidclamping plate having integral prongs driven into said base forconnecting the base and plate together, substantially as described.

In a brush, the combination of a handle base provided with groovesextending transversely of the bottom thereof, a ferrule extending aroundsaid base and having integral cross-bars fitting within said slots, saidferrule being fastened to said base by staples fitting over saidcross-bars and driven into the base, a clamping plate, bristles confinedbetween said clamping plate and said ferrule, said clamping plate havingintegral prongs driven into said base for connecting the base and platetogether, and a loose nail driven through a hole in said clamping plateand into the base for further securing the two parts together.

a. .In a brush, the combination of a handle base provided with slotsextending transversely of the bottom thereof. a ferrule extending aroundsaid base and having integral crossbar-s fitting within said slots, saidferrule being fastened to said base by staples fitting over thecross-bars and driven into the base, a tapering clamping plate havingintegral prongs extending from its inner face, said prongs being driveninto the base, bristles confined between said ferrule and said clampingplate and held therein by a wedging action of said plate, and fasteningmeans extending though said clamping plate and into said base, substantially as described.

in testimony whereof, I the said WILLIAM S. WALKER have hereunto set myhand.
